The Cigna Group vs UnitedHealth Group Incorporated Common Stock (DE)
Why these are rivals: #1 and #3 by market value ($365B vs $79B) in Nasdaq's "Medical Specialities" industry; SEC SIC 6324 / 6324 (same major group); #1 and #3 by market value ($365B vs $79B) with SEC SIC 6324 (Hospital & Medical Service Plans).
Rivals, but right now the price gap does not have a measured habit of closing, so there is no paper idea, whatever the gap.
